500 SS is literally impossible on howling abyss.

Literally?

your ult is also much more powerful there due to the limited space to move around.

seems fair imo.

'See you on the Rift!' -Riot, probably

Just use barrels on minion waves, they get you SS real fast

Its actually like 130 minions on SR, so if your not that great of a farmer its harder for you on sr :P. They should kinda do the Cassio passive on it. Get 5ss for every minute :)

Getting 400 stacks in twenty minutes as Nasus is also impossible on ARAM.

The game isn't balanced around ARAM.

Even on Summoner's Rift, the Plunder mechanic isn't entirely up to scratch. The Silver Serpents cost for each upgrade is too high as a baseline, but the lack of differentiation between small and large units also harms jungle , who is otherwise fairly viable. It's also in contrast to pretty much every other farming mechanic (e.g. Siphoning Strike stacks, Baleful Strike's AP gain, 's stacking health), which grants bonus rewards for killing large minions, monsters and champions.

you also only have a 1/125 to 1/116 chance of getting gangplank who can kill anyone he wants on aram(if it were really that simple for odds as someone else explained in another thread)
